     The Crystal Engineering HPC40 Series offers superior accuracy along with a host of user friendly features that allow this handheld pressure calibrator to deliver laboratory  accuracy in a portable field instrument.  The versatle HPC40 Series is suitable for calibrating pressures ranging from vacuum to 15 000 psi with accuracy of 0.035% of Reading for all ranges. It is ideal for process control applications, such as verification or calibration of pressure gauges, transducers, transmitters, pressure switches and valve stroking.

     The HPC40 Series also offers a mA loop calibrator that is fully temperature compensated from -20 to 50oC, enabling it to deliver the same accuracy whether measuring pressure, current, voltage or temperature.

     The HPC40 Series device can typically replace several gauges or calibrators. With the addition of a Crystal Engineering APM (Advance Pressure Module), the  calibrator can read up to three pressures at the same time using a single device and the differential pressure between any two. It is available in a single (HPC41) or dual sensor (HPC42)  version and it also can be used along with an RTD as a high-accuracy thermometer.

     The calibrator’s large, full-color display combined with its menuless interface makes the HPC40 Series the easiest pressure calibrator to use. Its single layer user interface has no convoluted menu structure, allowing tasks to be performed quickly and intuitively. Its intelligent memory slots allow the HPC40 Series to store up to five screens (both upper and lower windows) simplifying recall of previous stored settings and custom setups.  This is a big time saver for repeated testing. 

    Another unique feature is  its use of newly patented CPF Crystal Pressure Fittings. These 316 stainless steel fittings are designed to operate at 10 000 psi / 700 bar and ensure leak-free connections without the use of tools.  In addition, the fittings’ self-ventilating weep holes alert users when disconnecting from a pressurized system.

    The Crystal - Ametek HPC40 Series can be used as an individual calibrator or combined with AMETEK pressure pump systems to form a complete ready-to-use calibration system. These products include everything from small pneumatic hand pumps to precision, hydraulic pressure comparators able to generate up to 15,000 PSIG / 1000 Bar.
